  • COMBINED SPATIAL AND BIT-DEPTH SCALABILITY
    Publication number: 20100220789
    Abstract: Various implementations are described. Several implementations relate to combined scalability. One method is for encoding a combined spatial and bit-depth scalability. The method includes encoding a source image of a base layer macroblock. The method also includes and encoding a source image of an enhancement layer macroblock by performing an inter-layer prediction. The source image of the base layer and the source image of the enhancement layer differ from each other both in spatial resolution and color bit-depth.
